JANTXV1N971DUR-1

Single Zener Diodes Overview

The JANTXV1N971DUR-1 is a high-reliability Zener diode manufactured by Microchip Technology. It features a nominal voltage of 27 V and a maximum power dissipation of 500 mW. The device utilizes a silicon junction within a glass MELF DO-213AA (DO-213AA-2) surface-mount package. Qualified per MIL-PRF-19500/117, it offers a tight tolerance of ±2% and operates across an extended temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Military-grade reliability with metallurgically bonded internal construction
• Extended operating temperature range suitable for harsh environments
• High-stability voltage regulation in a compact surface-mount form factor

Single Zener Diodes Applications

• Aerospace voltage reference circuits
• Aviation power supply protection
• Military electronic system regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix 'DUR-1' against official Microchip documentation to confirm the exact reel packaging and RoHS status, as military variants often differ from commercial equivalents. Ensure the procurement channel provides traceability certificates required for MIL-PRF-19500/117 qualified components. Confirm lead times due to specialized manufacturing processes.

Single Zener Diodes Selection Notes

Select this component when a precise 27 V reference is required in space-constrained surface-mount designs. The ±2% tolerance ensures tighter regulation than standard 5% parts. Consider the DO-213AA footprint compatibility during PCB layout. Evaluate thermal management requirements given the 500 mW power rating in enclosed aerospace enclosures.

Single Zener Diodes Part Context

This part belongs to the 1N957BUR-1 through 1N992BUR-1 series of 0.5 W Zener diodes. These devices provide a wide selection of voltages from 6.8 V to 200 V. The series is characterized by its glass MELF construction and availability in JAN, JANTX, and JANTXV qualification levels for various military and industrial applications.

Single Zener Diodes Replacement Considerations

JAN1N971DUR-1: Lower qualification level. JANTX1N971DUR-1: Intermediate qualification level. Verify pinout and electrical parameters match before substitution.
